Shallow exhalation may yield inaccurate breath alcohol readings; leaves open standardization of exhalation protocols for testing.
Observational
Breath-alcohol concentration plateaus only after discarding at least 70% of vital capacity, highlighting the importance of deep exhalation for accurate breathalyzer testing.
Alan Wayne Jones (1982) conducted an observational in Healthy men. Moderate dose of alcohol was evaluated on Breath-alcohol concentration and breath-temperature as a function of expired-volume. Breath-alcohol concentration reaches a plateau only after discarding at least 70% of vital capacity, though it reaches 80% of end-expiratory levels after discarding just 10%.
